JEREMIAH KEITH, OF NEW BEDFOR-D, MASSACHUSETTS.

Specification forming part of Letters Patent No. 37,170, dated December16, 1862.

To all whom it may concern:

Be it known that. I, JEREMIAH KEITH, a citizen of the United States ofAmerica, and a residentof New Bedford, in the county of Bristol andState of Massachusetts, have invented a new and useful or ImprovedMachine for Punching and Eyeleting Shoes or other Articles; and I dohereby declare the same to be fully described in the followingspecification and represented in the accompanying drawings, of which-Figures 1 and 2 are side elevations of the machine, showing in red linesatreadle applied thereto. Fig. 3 is a top view of the said machine withthe cover of the eyelet magazine case turned backward. Fig. 4 is atransverse and vertical section taken through the eyeletmagazine, and soas to show its operative mechanism. Fig. 5 is a vertical andlongitudinal section taken through't-he punching and upsettingmechanism. Fig. 6 is a front view of the said machine.

' The object of my invention is to produce a .machine whichshall notonly punch or make the holes for the eyelets which are to be inserted ina shoe or other article, but introduce and properly fasten the eyeletsin such shoe or article.

In the drawings, A denotes the frame or table for supporting the.operative parts of the machine. 0n the rear part of the said table,

and extending upward therefrom, is-a rectt angular box or case, B, whichis provided with a cover, a, and has disposed within it a hopper oreyelet magazine, 0, which may be of a rectangular or any otherconvenient shape, and be furnished with a lid or cover, a, the saidmagazine being supported on an inclined platform or partition, b.Thesaid platform is so pivoted to the sides of the box as to allow it(the said platform) to have a vertical tilting movement, which,ofcourse,is imparted to the magazine 0. The said magazine has a stud ortooth projecting downward from its lower surface and extending through arectangular slotmade longitudinally through the The said stud or toothengages with or is operated by a sectoral gear, b, or semicircularplate, having teeth 0 0 arranged upon its outer surface. The said gearis supported by a pivot, e, which passes through it and into a verticalplate, d, as seen in Fig. 4. To one end of such gear a connec ing-rod,f,is attached and extends downward, and is connected to a treadle or anyother motor which may be employed to give'a vertical motion to thepunching and upsetting mechanisms, vertical or upward and downwardmovements of the rod f impart to the hopper reciprocating intermittentmovements, whereby the mass of eyelets are caused to arrange themselveswith their broader parts or flanges downward. The said magazine isprovided with a series of discharge-passages, g g, the same beingarranged at its lower front side and opening into the upper end of theinclined chute D, as shown in Fig. 5.

Fig. 7 is an inner side view of the front part of the hopper, showingthe discharging-passages. These passages have their greatest width attheir lower parts, and are to be of a size just suflicient to allow theeyelets to pass easily through them, when such eyelets are brought intotheir proper positions, the object of so making the said passages beingto cause apositive arrangement of the eyelets-viz., with their flangesdownwardbefore entering the chute D. The conductor or chute D isattached to the platform b, and consists of an' inclined tapering box,whose internal height should be slightly greater than that of theeyelets. which are to pass through the same, but not great enough topermit the eyelets to turn during their descent through the chute. Thelower part or discharging end of the said chute I form forked,in orderthat the lowermost eyelet mav have its lower end so exposed as to bereadily entered and carried forward by the seizer and carrier u,t0 behereinafter described.

E is what I term the retainer, the same being attached to'a standard, G,and consists of a thin fiexile spring, h, or its equivalent, so arrangedas to extend down and retain the lower eyelet in a proper position to beseized by the carrier before mentioned. This spring should be of such ayielding nature as to easily give away and readily allow the seizer totake the lowermost eyelet and carry it forward out of the chute orconductor.

H is a vertical slide-bar, which extends down through the table A, andhas its lower end connected with a cross-bar, 0 which is 'to be attachedto a treadle or any other motor suitable for imparting verticalmovements to it. To the upper end of the said bar a bifurto behereinafter described. The

were... I, is jointed, and extends atright angles therefrom, and has ablock, K, which carries a punch, L, on one of its ends, while itsopposite end is provided with what I term 'end.; The said pin,when-brought downward,

enters the eye of the eyelet,while the flat surface or shoulder Zcompresses the eyeletupon its top surface. The'said block Kis mountedupon a shaft, m, which extends horizontally through theforks of the barLand carries on one of itsends a notched wheel, M, which operates inconjunction with a spring catch or pawl, n, arranged on the side of thebar I, as seen in Fig. 1. .The said pawl is thrown .out of its'notchesby means'of a catch-lever or tripper, o, acting .upon the, rear partofsaid pawl, the whole being formed and arranged asshown in said figure.The other end of the shaft m'car'ries a friction-wheel, N,'whichoperates with a spring presser-bar, O, to give the proper rotary motionto the upsetter and punch L. This presser-bar consists of a rigid lever,having'a piece of india-rubber or other mate.-

rial suitable to produce friction applied to its .outer face. Said baris attached to two hori z'ontal slide-ba s, p p, which extendhorizontally through slots formed through a rectangular frame, 1?, whichis constructed and arranged as shown in the drawings, Figs. 1 and 2.Each of the said bars p'is encompassed by a helical spring, q, one endof which is connected to the inner face of the frame P, while the-otherend is atfixed to the said bar, the

object of such spring being to force the presses bar 0 out of actionwith the friction-wheel N. Furthermore, in orde'rto maintain thepresserbar and the friction-wheel N in contact at the proper periods forimparting to the block K, which carries the punch and upsetter, itssemirevolutions and intervals. of rest, a jointed lever or toggle-joint,Q, isdisposed within the frame 1?, and has its two ends passed throughslots in ade horizon tally through the said frame, as shown inFig. 2.The frontend of the said lever projects, when forced outward, throughthe frame P, and forces the said press'er-har 0 into engagement with thewheeLN. :Thev

devices for operating the said lever Q are two studs, 1" 1", arrangedupon a vertical bar, s, at

tachedl'o thebar I, before mentioned, so that when the latter isdraw'ndownward the upper stud, r, is brought in contact with the toggle, so asto bring the parts of the latter into a straight line, and thereby forcethe. presserbar against the wheel N and cause the latter to make asemi-revolution. When this is effected, the spring 1? causes theslide-bar H to be elevated and the lower stud, r, to strike against theunder side of the toggle and raise the same, and thereby throw it out ofaction upon the presser-bar, which, by means of the springs q q, isdrawn away from the wheel N, and remains out of contact with the latteruntil the toggle is again forced downward.

P is a coiled spring, which has one of its ends attached to thecross-bar Q while its.

other end is connected to the table A, as seen in Figs. 1 and 2, itsobject being. to elevate the slide-rodH and the-connecting-rod f, aftereach depression thereof.

R represents the frame for supporting the rotator S, which carriesondoneof it's ends a punching block-or bed, t, and on its other'end aneyelet -separator and carrier, u, and the mechanism by-which it isoperated. The-said punching-block is of a cylindrical orother convenientform, having a'flattopsnrface, and

serves to support th'eshoe while having its eyelet-holes punched; Thesaid eyeletrse'parator may be of a similar form, but should have a pinor stud, u, extending from its end, such pin resting on a spring, a,which allows the pin to be forced into the main partduring thedepression of the upsetter while fastening the'eyelet in theshoe.

T is the shaft of the rotator, which extends through the sides of theframe R,an d has its journals resting in suitable bearings formedtherein. One end of the said shaft carries a spur-wheel; U, whichengages with a pinion, V, arranged'on one side of the frame It, as shownin Fig. 2. 'The said pinion is supported and so as to be capable ofbeing revolved upon a pivot, 41, which passes through one side of theframe R W isa lever, which is arranged on the sai'df pin v and turns onthe same as afulcrum. On one end of the said lever a spring-pawl, u, is

disposed, the same, operating withthe pinion V, as shown in thedrawings,the other end of said lever being join ted to a connecting-rod, X,.whose other endis jointed, to an arm, Y, extending from the slide rodH. On the opposite end. of the shaft T a notched wheel, Z,

is arranged, and operates with a spring-pawl, x. Thesaid pawl is thrownout of engage inent with the wheel by means of a trippinglever, A, whichis jointed tothezbar 0 The said lever is constructed with a shouldernear its upper end, which operates with another shoulder madein the rearend of the longer arm of the pawl a: to throw the pawl outof en'-gagementwith the wheel Z, and allow the latter to be rotatedone hundredandeighty degrees. .The lever Aiis maintained in proper positionv withrespect to the pawl by'meansof the spring 3;, the whole being formed'anddisposed as shown in Fig. 1.

Havingdescribed the construction of my ,machine, I will'now describe itsoperation:

If we suppose the slide-bar H and the connect-- in g-rod f (which isattached to the mechanism for actuating 'the magazine 0-) to beconnected to a foot-treadle disposed below them, the up-* ward anddownward movementsof the treadle,

acting through the connecting-rod and the I sectoralgear bi, will giveto the eyelet-magazine longitudinal reciprocating intermittentmovements, which, acting in conjunction with the force of gravity,serves to bring the eyelets into proper positions for passing into theconductor D, the passing of the eyelets into the .hole.

guide or conductor being caused-by the verti 'cal tilting movementsimparted to the chute by 'thesudden. elevating action of the eyeletseizer and carrier while removing an eyeletfrom the retainer. Ifnow.we.sup'po se a sufficient number to have. been introduced into the."chute or conductor, and we also suppose the punch to stand with itscutting-edge downward directly over the punch-block, and if we alsosuppose a shoe or other article to be punched "to-be placed upon theblock, if, under these circumstances, the punch is depressed upon thepunch-block, an eyelet-hole will be made in; the leather of the'shoe. Next, the s'pring 1 will elevate the slide barH andbring it back to itsfirst. pfosition,causing,-in the meantime," .both the punch andpunch-block to-- be re:

volved one hundred and eighty degrees, and

g the upsetter andeyelet-carrier to be respectively brought into theposition just occupiedby the punch and punch-bed.- During.lsuch rotationthe eyelet carrier and separatorpasses into the eye of the lowermosteyelet in the conductor, forcessuch eyelet out from ,the springretainer,and carries it forward into the hole previously made by the punch. lfnext, we

again depress the treadle, the upsetterwill be brought down toward andupon the eyelet-car-r 'rier and its eyelet.

The stud u. of the eyeletcarrierbeing forced into its chamber, such eye!let will be compressed between the flat surcrate asset-forth;-

or article to be operated upon will have its eyeletholes punched andthe'eyelets .properly inserted and secured therein. 7

It will behevidentthat if the eyelet-holes were made in the shoe priorto beingoperated on by themachine the punch and punching bed might bedispensed with.- 'In this case all weshould have to 'do would be to putanother eyelet-carrier in the place of the punch bed and withdrawthestud ,1, (which forces the tog gle-lever against the Presser-ban) andthesaid' presser bar would have no action on. the friction-wheel N, andconsequently therewill "beno revolution of'the upsetter,but it will befree to have vertical. movements imparted to it as before, and will.operate with the eyelet separators and carriers,as before described..-
